Acarwash charges $8 per car and can wash at most 10 cars each hour. the amount the carwash earns in an hour depends on the number of cars washed. what is the domain of this relation? a. 0 ≤ x ≤ 10 b. {0, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80} c. {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10} d. 0 ≤ x < 80

{ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Step-by-step explanation:

Let x represents the number of car washed and y represents the amount of car wash,

Since, the amount the car wash earns in an hour depends on the number of cars washed,

That is,

y ∝ x

⇒ y = kx

Since, domain of the above function = all possible values of x

Also, there can at most 10 cars wash each hour,

Again,

x can not be negative or in decimal,

⇒ x ∈ { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Hence, Domain for the given relation = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

OPTION C is correct.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
